fix(iace): confirmation dialog for ungrouping + undo/regroup

- X button replaced with confirmation dialog: "Als eigenen Punkt fuehren" / "Abbrechen"
- Dialog explains the action and that it's reversible
- Ungrouped items show orange "Zurueck in Block" button
- Info bar shows count of ungrouped items + "alle zuruecksetzen" link
- No destructive action without user confirmation
